Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Armed with a computer model in 1935, one could probably have written the exact same story on California drought as appears today in the Washington Post some 80 years ago, prompted by the very similar outlier temperatures of 1934 and 2014.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

NSA: Coda

First, Roger asserts that the executive and legislative branches would not be “co-equal” if Congress is permitted “to restrict the president’s powers, as with FISA.” “Congress,” he adds, would then be “supreme, the president its mere agent.” Not true. Before any restrictive measure can become law, it must be passed by Congress and signed by the president. FISA was of course signed by President Carter. Neither successive presidents nor successive legislatures are required to re-validate previously enacted, unexpired statutes. Moreover, FISA was implicitly re-signed by George W. Bush, who helped craft the FISA amendments that are included within the PATRIOT Act and prescribe surveillance warrants.

Second, Roger notes that Congress can always avail itself of the “power of the purse … and simply cut off funds for projects.” My response is threefold: (1) A constitutional regime that would allow Congress to eliminate a project altogether, but not restrict a project, is quite simply incoherent – especially if the project arises, as Roger insists, out of an inherent presidential power. (2) The NSA surveillance program is secret to all but a few members of Congress. Accordingly, Congress might have to de-fund the entire NSA in order to pinpoint and de-fund one program, the scope and function of which is mostly unknown. (3) Even if Congress could de-fund the program itself, that would throw the baby out with the bathwater. Republicans and Democrats alike conjecture that much of the NSA program may be necessary and effective, albeit illegal, in combating terrorism. The responsible remedy is not to de-fund an essential program, but either to change its implementation to comply with the law, or change the law to authorize the program.
